摘要

摘要动力两轮车在世界范围内的交通事故统计中占比过高，目前可用的安全解决方案并没有引发减少的趋势。为了挽救骑手的生命，开发了一种新的装置概念，包括一件可穿戴的背心，背心的背面缝有皮带条纹，并通过金属电缆固定在摩托车车架上。本文的目的是从ISO 13232数据库中选择一组具有代表性的崩溃配置来评估其保护有效性。在多体环境中再现了这些构型，并通过以下参数对每种构型进行了表征:冲击速度、接触点、相对航向角和安全装置的布尔存在。初步评估显示了令人鼓舞的结果，因为几个身体区域报告的损伤指数降低了。然而，这些好处取决于速度范围和冲击配置。总的来说，在选定的事故数据库中，收益超过了额外的风险。关键词:约束装置摩托车碰撞防护设备伤害预防碰撞模拟被动安全披露声明作者未报告潜在利益冲突。本研究未收到任何私人或公共资金。

Preliminary evaluation of a passive safety device concept for the protection of riders

AbstractPowered Two-Wheeler riders are over-represented in crash statistics worldwide, and currently available safety solutions have not triggered a decreasing trend. A new device concept, comprised of a wearable vest with belt stripes sewn on the back and fastened to the motorcycle frame through a metal cable, was developed to save riders’ lives. The objective of this paper is the evaluation of its protective effectiveness in a set of representative crash configurations selected from the ISO 13232 database. The configurations were reproduced in a multibody environment, and each of them was characterised through the following parameters: the impact speeds, contact points, relative heading angle, and the Boolean presence of the safety device. The preliminary evaluation revealed encouraging outcomes as several body regions reported reduced injury indices. However, the benefits depended on the speed range and impact configuration. Overall, the benefits outweighed the additional risks in the selected accident database.Keywords: Restraint devicemotorcycle crashprotective equipmentinjury preventioncrash simulationpassive safety Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingNo private or public fundings were received for this research.

期刊介绍： International Journal of Crashworthiness is the only journal covering all matters relating to the crashworthiness of road vehicles (including cars, trucks, buses and motorcycles), rail vehicles, air and spacecraft, ships and submarines, and on- and off-shore installations. The Journal provides a unique forum for the publication of original research and applied studies relevant to an audience of academics, designers and practicing engineers. International Journal of Crashworthiness publishes both original research papers (full papers and short communications) and state-of-the-art reviews. International Journal of Crashworthiness welcomes papers that address the quality of response of materials, body structures and energy-absorbing systems that are subjected to sudden dynamic loading, papers focused on new crashworthy structures, new concepts in restraint systems and realistic accident reconstruction.
